Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional mechanical means such as setting screws are used to adjust the armature stroke, then the pivoting or folding stroke can be adjusted, but the device complexity and seal complexity increase
Solution Approach 1:
The patent removes the complex mechanical adjustment means (setting screws, adjustment mechanisms) from the valve device. Instead, the armature stroke is adjusted by varying the thickness of the armature during manufacturing, extracting the adjustment function from mechanical components to a manufacturing parameter. This eliminates the need for additional mechanical assemblies while maintaining adjustability.
Solution Approach 2:
The patent replaces the mechanical adjustment system with a manufacturing-based solution. The armature stroke is determined by the armature thickness, which is controlled during manufacturing processes. This substitutes complex mechanical adjustment means with a simpler manufacturing parameter, reducing device complexity while preserving adjustability.
2Adaptability or versatility
If additional mechanical means are used to adjust the armature stroke, then the stroke can be tuned, but the sealing complexity increases due to changed pressure conditions in the armature space
Solution Approach 1:
The patent extracts the stroke adjustment function from the sealing system. By determining the armature stroke through armature thickness rather than mechanical adjustment means, the sealing arrangement is simplified to only require sealing the armature space without additional seals for adjustment mechanisms. This reduces sealing complexity while maintaining tuning capability.
Solution Approach 2:
The armature thickness itself serves the dual function of both defining the stroke and simplifying the sealing arrangement. The manufacturing process of the armature automatically provides the stroke definition without requiring additional sealing components, allowing the system to self-serve the adjustment function without increasing sealing complexity.
3Adaptability or versatility
If generic hinged armature valve devices are manufactured with additional mechanical adjustment means, then stroke adjustment is possible, but cost-efficient mass production is limited
Solution Approach 1:
The patent replaces mechanical adjustment means with a manufacturing parameter (armature thickness) that can be controlled during automated manufacturing processes. This substitution enables cost-efficient mass production by eliminating manual or complex automated adjustment operations, while still providing stroke adjustability through manufacturing variations.
Solution Approach 2:
The patent changes the approach from mechanical adjustment to parameter-based control during manufacturing. By controlling the armature thickness parameter during manufacturing, the stroke is determined without requiring post-manufacturing adjustment mechanisms. This parameter change enables cost-efficient mass production while maintaining adjustability through manufacturing process control.
